To all whom it may concern:

Be it known that I, ALVIN A. HANKE, a citizen of the United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Spring Susensions, of which the following is a spec cation.

This invention relates to a sprin suspension for power driven vehicles an more particularly to that type of vehicle used for passenger service, although it may be applied, with slight modifications, to vehicles used for trucking. v t I It has for its principal object the provision of means whereby the horizontal as well as the vertical re-action of the wheels of the vehicle are absorbed without disturbing the line of motion of the bodyand the Hidependent action of the wheels while performing this duty. v v 1 A further object of the invention is in the provision of means whereby variable independent re-action of the wheels when encountering different sizes of obstructions is consumed without disturbing the line of motion of the body. I p 7 Q -The foregoing may be accomplished in the embodiment of my invention shown in the drawings forming part of this specification. 7

In the drawings, wherein like reference numerals designate similar parts throughout the various views, Figure 1 is a side elevation of the device shown applied to the rear wheels of the vehicle, the wheels being indicated in the figure in a dot and dash line; Fig. 2 is a sectional plan indicated by the line 2-2 of Fig. 1; Fig. 3 is a sectional detail of the driving mechanism as indicated by the line 3-3 of Fig. 2; Fig. 1 is a rear elevation; Fig. 5 is detail on the line 55 of Fig. 1; Fig. 6 is a similar detail on the line 6-6 of Fig. 1 and Fig. 7 is a sectional plan of the differential mechanism.

The device comprises the usual channel frame 1 which in this case stops short of the rear axle. Secured to each side member of the frame and close to the end is a bracket 2, said bracket pivotally supporting at its upper end a link 3, this link provides a swinging pivotal bearing at 4; for a lever 5, said lever being secured to a link 6, which is supported by the rear axle hous' ing 7. Intermediate of these two points a shacl le 8 has pivotal connectlon at 9 to Specification of Letters latent.

- the lever 5 and engages at its lower end the eye of a spring 10, said spring being rigidly -fixed to the frame 1 by means of the bracket l1.-secured thereto, said spring may be of the cantaliver type if desired. This construction is duplicated u on the opposite side of the vehicle, an strengthened by the rod 30 which extends between" the pivot points of the brackets 2.

Referring particularly to Figs. 1 and 7 it will be seen that oweris appliedto each individual wheel a lowing thereby an independent motion for eachwheel.

A power shaft 12 having connection with is transversely the motor of the vehicle has a bevel pinion 13 meshing with the ring gear of a differential mechanism indicated generally at 1 1, and supported upon a transverse split shaft 15' supported within the housing 16. The shaft 15 is provided with miter gears 17 meshing with similar ears 18 upon the shaft 19 extending at rlght angles thereto and extending rearwardly to the axle and provided with universal joints 20 between the gear'18 and the gears 21 upon the rear axle,thegears 21being supported in a suitable housing carried by the rear axle, this provides an independent drive for each rear wheel. The shaft 15 extends beyond the housing 16 where it is sup rted within bearings (not shown) secure to the frame 1. Brake drums 22 are secured to the shaft andIa-re provided with internal and external'brake bands 23 which may be actuated will be inclined forwardly with respect to 1 the pivot 30 when the vehicle is in forward motion. Any minor re-action will be upwardly and easily absorbed by the righting of this link.

Through the agency of the link 6 and the link 3 the jar and jolt produced by the shift ing tooquickly from low speed to a higher speed or the sudden starting or stopping of the vehicle is reduced to a minimum, the reaction of the links require little force to be exerted on the spring.

not only take care of the vertical butalso'the horizontal re-action.

Furthermore, a more resilient action is secured since any obstruction encountered.

will lengthen the lever arm 5 through the ree t on f the p int 7 while th l e annef the' pr ng thr ugh he po is no me erillyr l ng en d nd t a th e gh th sv ine ge on le e arm ver the eth r .1 will secure a greater force producing Idefle ti f t e sp ng n co equ n ly an easier deflection. 7

While I have shown and 'deseribedthis sp eifi form in t e eb v e e ipt en, i v iden h t arious modifica ions of t ein may be s d end I do no Wi h to l m t myse fu her han is 'eq r y h state of the art and that which is within the scope of the appended claims.

I claim: f

The combina ion with a vehicle frame, sidespring fixed thereto and axle housing, of a lever, links connecting opposite ends of the lever and the frame and housing re.- spectively, and a link connecting the lever and the spring.

2. The combination with side spring fixed thereto, behind the frame,

a vehicle frame, andaxle housing of a lever flexibly connected to the frame andthehousingres peetively, and a link connecting the lever and the free rear-end ;of the spring.

3. The combination with a vehicle frame,

side spring fixed thereto, and a floating axle housing behind the frame, of a lever, a swinging linkconnecting the front end of the lever to the frame, a swing link connecting the rear end 'of'the lever to the axle housing, and a swinging link connecting the rear-end of the spring and the lever between t e ends of the lett an t t low r nd to t e reer en et t rin I The combination withe h ele fram ing id ,SiHSy-Q epa ate eer ,exleh ns- Ing n .eXl in eeh mus g, sp ine -be tween said housings frame, a wheelnpon h O ter end o fleeeh ex e, ed fier ntial dr v ng gea betwee side sills of the "frame, end a during eenn eticn w en sa d geer and th inner-end 10f .ea axle,
